The worst news was for Scott Walker. Once the front-runner in Iowa, the Wisconsin governor now registers less than 1 percent after the debate watched by 23 million people.

“I’m a little surprised,” Trump said of his drop on CNN’s “State of the Union,” “because other polls have come out where I’ve actually picked up after the debate.” An online Drudge Report survey found Trump won the debate, but this was the first scientific national poll after the big contest.

Trump also blasted Fiorina, saying she “did a terrible job” at the helm of Hewlett-Packard. “She’s got a good pitter-patter, but if you listen to her for more than five minutes straight, you get a headache,” Trump said on ABC’s “This Week.”

Doing an in-depth interview on Fox News Sunday, Fiorina defended her record at Hewlett-Packard, saying she was “proud of what I did at HP” during “the worst technology recession in 25 years.”

In an emotional segment, Fiorina recalled losing her step-daughter and battling cancer. “When you face a life-threatening or a tragic situation, you lose a lot of fear,” Fiorina said. “And so the things that might have caused you to be afraid about something — I’m not afraid. I’m really not afraid.”
